Application filed August is, 1905, Eerie! No. 274,251.

. clear, and exact description the same, such ticker t as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in printing telegraph systems, and particularly to What are known as stock-ticker systems, and my invention consists in the combination, with means for operating a two- Wire ticker or printer circuit from a distant transmitter by means of a single line circuit, of repeating means whereby the signals transmitted through such single line circuit may be repeated into a further line circuit for op crating tickers or printers at still another point.

The invention herein described comprises an improvement upon, and an extension of,-

the system illustrated and described in my applicationfor Letters Patent, filed April 2-2, 1905, Sr. No. 256,867.

The objects of my invention are, to permit a single transmitter and single line circuit,

or, more properly, a consecutive series of single line circuits. to control and effect the operation of multiple wire printers at a plurality of points; to permit repetition of signals from one line circuit of such a s stem to another; to permit the use of simp e and reliable apparatus; and generally to make.

the system simple, reliable, easily to adjust, and inexpensive.

In the accompanying drawings, Figure 1 indicates diagrammatically one embodiment of invention, Fig. 2 shows similarly an alternative arrangement of a portion oi: the repeating transmitter; and Fig. 8 is :1 diagrari'nnatic perspective illustrating diagrammatically the essential features of a twowire ticker such as referred to herein.

i will describe my invention with particular reference to the two-Wire printing telegraph illustrated and described m U. S. Let'- tersfl atent'to'Phelps, No. 726,556, dated April- 28, 1903.1]3l1e f mprinting" instrument shown in said patent is of the general stoo s raj etness atrshsf ens one embodiment o spring1hotor, their rotation being controlled by an escapement-ma net and escapement mechanism controlled tw erebyl Said printer also comprises a press magnet in. the same circuit with the escapernent magnet and erin said circuit; and said printer further comprises a shift magnet and a spring-Winding magnet, both located in the same circuit, which is separate and distinct from the cit ranged to be operateilby a prolongedpulse cuit of the escapeinent and oress magnets;

the spring-winding magnet being operate by periodic current pulses in said secondcircuit, independent of their direction, and the shift magnet being operated by reversal of direction in current in said second circuit; In the present system, as in that of my aforesaid applioationSr. N 0. 256,867, the various signals from the transmitter are transmitted through a single line circuit to translating mechanism, by which the signals for the operation of the escapement and press magnets of the printer or printers are transmitted through the corresponding local cir- The employment of single line circuits extending from a transmitting point to a plurality of points at which tickers are to be op erated, in connection with repeating appliances for repeating from one such line on:- cuit into another, renders it "economically practicable to operate circuits of printing telegraphs or tickers at a plurality of iocalities from a sin le distant city or locality, For example, by t is system herein descrilied I may operate ticker circuits in the cities of Philadelphia, Baltimore, l/Vashingtcn, Richmond, etc., from a single transmitter locate in New York, repeating from Philadelphia to Baltimore, again re eating from- Baltimore to Washington, an again repeating from Washington to Richmond; and so on.

In the accompanying drag/mg 1. illustrate g hmma i l yt ill tha ctrmrastid p ice rr Edit,

anvention dia- 1- ted heing well understood, and I do not illustrate the sunflower 3, said arm being carried by circuit ,WllGIl a key 'of either bank is depressed the pliances. Said drawing shows diagrammatreally, at A, the transmitting apparatus and circuits, and at B the translating and repeating apparatus and circuits, together with a series of printers controlled-by the translating apparatus; the two stations, A'and B, being connected by a line wire L, which may be of considerable length, as may line wire L, connecting station B with a further station, not shown. v

The various arts of the transmitting mechanism are il ustrated diagrammatically only, as the construction ,of these parts is construction of the receiving rinters as these are fully illustrated and cescribed in the said Phel s patent No. 726,566.

Referring fiist to the transmitting ap aratus, at A, 1. designates a revoluble s aft, driven in any suitable or customary manner, and 2 designates the rotary contact arm of a shaft 1.

4 and 5-designate the two banks of keys of a suitable keyboard, only three keys of each bank being shown, though it will be understood that in practice there will be a much greater number. The keys of both banks are shown arranged to make contact, when depressed, with a common row of contact points located between the banks of keys.

6, 6, 6 designate neutral relays each electrically connected to and controlled by a corresponding key of bank 4 and also by a corresponding key of bank 5; the contact point of each relay 6 being connected to a corres onding contact segment of sunflower 31- O viously, the arrangement is such that corresponding relay 6 is energized and the in the corres onding sunflower segment is completed. n the said Phelps patent above mentioned, the transmitter "keys are connected in circuit with their corresponding sunflower se ments directly; but in practice it is preferable to cause the keys to operate relays controlling the circuits of the sunflower segments, as here shown.

7 desi ates a generator supglyin current for loca purposes, and 8 an 9 c esignate positive and negative current leads therefor.

10 designates a ratchet wheel on shaft 1, 11 a stop magnet, and 12 the armature of said magnet, a apted, when the ma at is energized, to engage said ratchet w eel and a'rrest the rotation of shaft 1. Said magnet is in a local circuit 13 passing from current lead 9 through magnet 11, to the rotating arm 2 of the sunflower and thence, when said arm makes contact with a sunflower segment the circuit of which is completed by the corresponding relay 6, through such sunflower segment and rela It follows, there ore, that when one of the transmitter keys, of either bank, is depressed,

contact to current lead 8. the magnet of ceases as soon as the sunflower contact arm makes contact with the sunflower segment corre sponding to that key, stop ma et 1 1 is energlzd, and the rotation of sha t 1 is stopped until said key is released. L

Shaft 1 carries a commutator, 14, of wellknown construction, the brushes of which commutator are included in a circuit 15 passing from current lead 9 through the commutator and the magnets of'two polar relays 16- and 17 back through the commutator to current lead 8. This commutator reverses the direction of the current in circuit 15, as shaft 1 rotates, causing the armatures of relays 16 and 17 to vibrate back and forth.

\ Numerals 18 and 19 designate two similar enerators, for sup lying current to the line, aving unlike brus es connected to ground at 20, their other brushes being connected through wires 21 and 22 to opposing contact stops of rela 16. The armature of this relay is connecte by wire 23 to the two contact stops of relay 17; and the-armature of said latter relay is connected, through means hereinafter described, to the line circuit L.

Since the armatures of relays 16 and 17 are vibrating back and forth rapidly while transmitter shaft 1 is rotatin generators 18 and 19 are connected'tothe fine'alternately, and

thus the current in the line is reversed ra idly while shaft 1 is rotating. So far as tl fe alternate connection of the two generators 18 and 19 to the lineis concerned, a single polar' relay might be used but it i'sfound that by emloying two relays, arranged as shown, and

'y connecting a condenser 24 across the stops of relay 16, as shown, the sparking at the contact points and brushes may be reduced greatly.

Numeral 25 designates a polar relay employed for efi'ecting the operation of the shiftmg devices of the receiving printers. A circult 26 passes from a universal contact bar of the bank of keys 4 throu h one of the two olpposed magnets of this re ay to wire 27 and t ence to-current lead 8. This circuit will be completed wheneverone of the keys 4 is depressed. A similar circuit 28 passes from a universal contact bar of the bank of keys5 to the'o'ther of the said two opposed magnets of relay 25 and thence to wire 27 and so to current lead 8. This circuit will be completed when any one of the keys of bank 5 is de ressed. Relay 25 controls the circuit 29 rom current-lead 8. through the-contact of said relay to themagnet of a relay 30, which may be termed the shift relay and thence back to current lead 9. This circuit is broken when circuit 26 is complete but is closed when circuit 28 is complete. Another relay 31, termed the repeat relay, is in a circuit 32 which passes from current lead 8 to relay 3'1 and thence to a re peat key 33, arranged when operated to close said circuit, and back to current lead 9.

The operation of the shift mechanisms of Y the several printers is accomplished by reversing shedirection of the current in this circuit 56, which reversal occurs when relay 30 is euesgized, so that resistance 37 is included in the line circuitund the leak 39'is connected to said line circuit. When this occurs, the strength of the line circuit is so reduced that the armature of relay is culled buck, and circuit 56 is connected to the opposite current- .lesd, 44. When relay is sgeiuenergized sud cuts resistance 37 out the hue circuit and disconnects the leak 39, the-armature of relay 50 is again atirs-steal, and the direction of current in circuit -fi is again reversed, thus operating again the chili mechanism of the riuters'.

the armature of relay 31 is connected to the outgoing line, L. A resistance 37 is shunted across from the armature of relay 16 to the armature of relay and the stop of re lay 30 opposite to that stop to which the armature of relay 16 is connected, is grounded through a resistance leak 39. Relay 16' repeats into circuit L the reversals in circuitL When, through the operation of shift relay 30, the strength of the is restored to full value.

current in circuit L is reduced, and relay 50 is operated, reversing the direction of current in the local shift circuit 56, this reversal operates relay 30, breaking the shunt through its armature by which resistance 37 is rendered ineffective normally, and connecting leak 39 to circuit L, so reducing the strength 01 current in circuit L to correspond to the reduction of current strength in circuit L. Similarly, when by the operation of relay 30 the strength of current in circuit L is restored to full value, relay 30 is also operated and the strength of current in circuit L When, by the operation of relay 31, the strength of the current in line L has been reduced to such extent as to operate relay 48, the magnet of relay 31 is energized, and thereby the high resistance 41 is thrown into line L thus similarly reducing the strength of current in circuit L. It will be seen, therefore, that relays 16, 30, and 31, with their circuits, constitute a complete repeater for repeating into circuit L all of the current fluctuations and reversal of circuit L, so that if translating apparatus and tickers such as are located at station B be located at the distant end of line L, the same will be operated 'ust as the, corresponding apparatus and tie ers at station Bare operated. It will also be seen that by locating at the distant end of station B, repeating devices such as relays 16', 30, and 31', and

corres onding circuits, signals. may be. re-

, peater into still anotherhne circuit, and so -might be provided contact points, one ,for the local ticker circuit on, through a number of line circuits and translating and repeating apparatus. Since relay 16 merel lay 45, it is o vious that the latter relay with two separate sets of and the otherfor line circuit L, and thereby some complication maybe saved. This is- The principal reason illustrated in Fig. 2.

sets for for employing separate enerating the local ticker circuit and for the line circuit is that a higher potential is. customarily emrepeats the operation of r'e-' ent controlling means, printing and s t cirployed in said latter circuit than in the local at ticker circuit.

The printers or tickers of the type referred to herein are customarily provided with spring winding mechanism operated by successive current pulses in the shift circuit 56. Various means may be employed for roducing such successive pulses. I have illustrated one such means, comprising an alternating current generator 57 in a local circuit 58 controlled by line relay 52 and controlling a relay 51. I The retractile spring of relay 52 is so adjusted that circuit 58 is complete only whenthe strength ofthe line current is re duced owing to the presence in said circuit of resistance 37 or resistance-41; such resistances being in circuit, in practice, sufliciently often for the purpose, and some complication being avoided by having the springwinding device operate with one direction of current only in circuit 56. When circuit 58 is complete, the operation of generator 57 causes the vibration of the armature of relay 51, causing the alternate breaking and completion of circuit 56 without changing the polarity of the current in said circuit, and

' therefore without affecting the shift mechanism of the printers P. i 4
